Sarcoidosis cardíaca, un desafío diagnóstico. Reporte de dos casos

Abstract

Cardiac sarcoidosis is underdiagnosed; it may occur in asymptomatic patients or be fatal as a consequence of severe arrhythmias, sudden death and refractory heart failure. Immunosuppressive treatment can improve the course of the disease. Two clinical cases with previously known sarcoidosis are presented and in the evolution cardiac sarcoidosis is diagnosed. In the first case, the diagnosis was made by means of myocardial biopsy during valvular replacement surgery, and in the second case by positron emission tomography requested for suspicion of cardiac sarcoidosis, when presenting palpitations and sinus arrhythmia. Clinical, diagnostic and therapeutic aspects are discussed.
